If you're going to weigh them on a scale, then be fair and clear off all the files from that 7200rpm drive, first ...
I'm an x31 owner/lover. I've even considered (and still do) upgrading to the S10, but the nearly-full-sized keyboard of the x31 wins out compared to the S10 (which is still much better than, say, the Aspire One). Plus, even with the 1.4GHz model (mine), 1.5GB RAM under WinXP and I've got a 30 second boot time, which is fine for my needs. (Though nothing boots like my old C-64.

) I've also been told (but have no hands-on proof) that the X40 HDDs are notoriously slow, and their 1.8" form factor makes upgrades a pain to do.
[edit: that's old data -- there are plenty of 1.8" drives these days, even SSD media]
